A syndrome consisting of the sub-syndromes reflex sympathetic dystrophy (RSD) and causalgia, also known as CRPS 1 and CRPS 2, or Type I and Type II, and characterized by chronic pain that typically affects a hand or foot (and then later spreads to the whole limb). CRPS usually develops after an injury, surgery, stroke or heart attack, but the pain is always abnormally intense for what would be expected with the initial damage, if there is initial damage at all.
